Re: Best House batteries
They work great until they don't! With LiPo batteries implementation is critical along with heat management.

Re: Best House batteries
AGMs save you the maintenance but in my experience don't last that much longer.
It s hard to answer the original question without knowing the charging system setup. If they're all on the same charger then you re going to have to pretty much match them. If they're on different chargers then you can use 8Ds for the engines and anything for house. I like golf cart batteries for house and inverters as they are easier to handle nPascal

Re: Best House batteries
Lithium iron phosphate.
LiFePo. Spell check is a pita.
It was not the battery chemistry in that building article.
Lithium iron phosphate is safe, will not burn, is extremely efficient and each cell is individually managed in high quality batteries
I work with this technology a lot.
It's far superior to any other Battery Technology for solar homes, inverters and other critical Power SystemsScott

It's all part of the integrated system we sell.
There's a network between the battery electronics making the bank a system.

Re: Best House batteries
At 3.2v per cell, it seems like they could make a 32v bank. There's probably not enough demand for that to build the charging system. I wonder if some other 32v charger could be used?

Re: Best House batteries
Regardless of what battery brand and technology that you choose, keep in mind that you won't get the best battery life possible without proper temperature and voltage optimization. I made a number of changes to my system that got me there:
Better battery box ventilation
Completely separate charging management of the starting bank vs the house bank. Without this the starting bank gets constantly overcharged. That can be 2 chargers or independently managed charging channels.
Temp sensors on the batteries to modify the voltages as the battery temps change and shut down if something nasty happens
I went even further and put Balmar regulators on my engine alternators so that my batteries get the optimum charging stages when running. That included taking the generator alternator out of the circuit so that this does not interfere with the Balmars eventually going to float.

Re: Best House batteries
4 cells per battery.
The cool part is the battery manager fixes all the balance and charging problems without guessing. I add Balmar alternators and set them at 80% so they don't burn up as the low resistance of the batteries would make them think it needs 100% all the time.Scott
